Cubresa NuPET™ name and logo

MRI-Compatible Preclinical PET Scanner

Cubresa's NuPET™ is a revolutionary in-bore PET scanner that inserts into existing MRI instruments to create a powerful and flexible hybrid preclinical in vivo imaging platform that combines the molecular sensitivity of PET with the superior anatomical, structural, and functional information of MRI.

Researchers using simultaneous PET/MRI imaging can measure multiple physiological processes concurrently with exceptional tissue contrast, quantitative accuracy, and study throughput.

Discover links between molecular mechanisms and functional response

Sequential PET/MRI scanning captures data at different times, making it difficult to analyze important functional relationships when animal physiology can change within minutes. With NuPET's simultaneous scanning, PET and MRI work in unison to capture time-synchronized and highly complementary information previously unattainable – so you can trailblaze a path to new discoveries.

Quantify with new confidence

Exceptionally precise PET/MR image co-registration and paired PET and MRI data points unleash advances like MR-based motion correction and partial volume correction (PVC) that increase PET quantitation accuracy. With MRI’s high soft-tissue contrast, VOIs can be accurately drawn using anatomical data with no guesswork. Shorter anesthesia duration helps minimize animal stress and reduce the risk of inducing physiological changes that can affect study quality.

Accelerate study throughput

Concurrent PET/MRI acquisition maximizes efficiency and helps make optimal use of tracer batches. The NuPET scanner can be quickly inserted and removed, making integration into any high throughput MRI facility easy.
